MERRILL COLVIN, OF ROCHESTER, NEW YORK.

HEAT-RADIATOR.

Specification of Letters Patent No. 9,048, dated June 22, 1852.

To all whom it may concern:

Be it known that I, MERRILL (30mm, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Heat-Radiator which I apply to any stove for the purpose of saving heat which would be otherwise lost or pass 011' through the stove-pipe or flue; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a perspective view, Fig. 2 is a longitudinal sect-ion through Fig. 1, Fig. 3 is a transverse section through Fig. 1. Fig. 2 is also a section through A, B, Fig. 3, and Fig. 3 is a section through C, D, Fig. 2.

E, Fig. 1 shows the outside plate of a cylindrical flue.

F F Fig. 1 show the inside plate of a cylindrical flue.

G Fig. 1 shows a pipe or receiver which passes through the cylinder.

H Fig. 1 shows a flue which passes up into the receiver G.

I, I, Fig. 1 show a flue which passes up through the stove into the cylindrical flue which is formed by the plates F F and E.

J Fig. 1 shows the top of the stove.

K Fig. 1 shows a pipe through which the smoke passes off.

L L Fig. 1 are pipes which are made in a -semicircular form and are attached to the ends of the pipe or receiver Gr at the lower ends and to the pipe K at the upper ends.

M Fig. l is a pipe which is attached to the pipe K.

N N Fig. 1 show one of the heads or ends of the flue which is formed by the plates E and F F.

0 Fig. 1 shows the end of the flue H; the opposite end is constructed in the same manner; the fire passes from the stove up through the flue I, I, into the cylindrical flue, and passes up into the upper part of the flue and then down to the lower part of the flue, up through the flue H into the pipe or receiver G; from the pipe or receiver G the fire passes out at each end, into the pipes L L, from the pipes L L into the pipe K, and from the pipe K into the pipe M, which leads to the chimney or flue.

P Fig. 1 shows an opening which extends to the opposite end of the cylinder; the air circulates through the opening P between the cylindrical flue and the pipe or receiver G where it becomes heated and passes out at each end of the cylinder which forms the cylindrical flue.

Q Fig. 2 shows the inside of the pipe M Fig. 1.

R Fig. 2 shows the inside of the pipe K Fig. 1.

S, S, Fig. 2 show the inside of the pipes L L Fig. 1.

T Fig. 2 shows the inside of the upper part of the cylindrical flue.

U Fig. 2 shows the inside of the pipe or receiver G Fig. 1.

V Fig. 2 shows the inside of the flue H Fig. 1.

WV Fig. 2 shows a section of the top of the stove J Fig. 1.

X Fig. 3 shows the inside of the flue M Fig. 1.

Y Fig. 3 shows the inside of the flue K Fig. 1.

Z, Z, Fig. 3 show a section of the outside of the plate of which the cylindrical flue is formed.

a, a, Fig. 3 show a section of the inside plate of which the cylindrical flue is formed.

Z), 6, Fig. 3 show a section of the plate which forms the pipe or receiver G Fig. 1.

c 0 Fig. 3 show the side plates of which the flue H Fig. 1 is formed.

(Z Fig. 3 shows a section of the top of the stove shown J Fig. 1.

6 Fig. 3 shows the inside of the flue shown I I Fig. 1.

f f f Fig. 3 show the inside of the cylindrical flue.

g Fig. 3 shows the inside of the flue shown H Fig. 1.

h Fig. 3 shows the inside of the pipe or receiver shown G Fig. 1.

a Fig. 3 shows an open space for the purpose of letting the air circulate bet-ween the receiver and the cylindrical flue; the open space i is the same as shown by P Fig. 1.

The fire passes up the flue a Fig. 3, and through the cylindrical flue f f f, and around into the flue g, and from the flue 9 into the receiver h. The receiver h Fig. 3 is the same as shown U Fig. 2; the fire from the receiver U Fig. 2 passes up through the pipes S S into the pipe R and out through Q Fig. 2.

Now it Will be seen by my peculiar arrangement of flues and pipes, I get-a large amount of radiating surface in a small compass; my radiator may be used on the top of a stove of any description either for Wood or coal, or it may be inclosed and used as a furnace.

Having described the construction and v operation of my heat radiator, What I claim
